Details

Dual-edge and better clearance over the body! This well-balanced steel fret file is offset, for more comfortable fret dressing and improved clearance at higher frets.

Both full-length concave filing grooves (one for narrow/medium fretwire, and one for medium/wide wire), are uniformly coated with micro industrial-diamond particles. 8-1/2" x 1" x 5/32". Available in either 150-grit or 300-grit.

Sold individually or SAVE when you buy the set of both files.

Diamond fret files are the best way to recrown your frets! Unlike traditional fret files, diamond files cut in both directions, they don't chatter or leave chatter marks, and the fret is smoother after crowning. These files are being used by repair shops and major manufacturers all around the world.

Our diamond fret files have concave cutting edges, one for medium and one for wide fretwire. Each edge is electro-coated with micro industrial diamonds. These super-tough abrasive surfaces round the frets more smoothly than standard toothed files, for cleaner filing without chatter marks. Because the diamond particles cut on the forward and backward strokes, you get better control over your work and the job goes much faster.

We offer three designs of diamond fret crowning files, each in two different grits. Diamond fret files are available in the traditional Diamond Fret File, the curved Offset Diamond Fret File, and the unique Dual-grit Diamond Fret File.

If you're use to traditional fret files, you'll probably be most comfortable with the Diamond Fret File, but you may find the curved design of the Offset Diamond Fret File may allow you to work more comfortably with less arm, wrist, and hand fatigue. Offset Diamond Fret Files are also excellent for working on the frets in the upper registers of acoustic and set-neck electric guitars. They virtually eliminate the chances of gouging the top.

What grit do I need? If you're just starting out in fretting, we recommend the 300-grit files, as they don't remove too much material too soon — a mistake that many beginning fretters make. Even a professional will find the 300-grit file allows them to quickly get the fret properly crowned after only a few strokes.

Use the 150-grit when you need to mill-off lots of material in a hurry.

Works on stainless frets, too!
All of our tools are suitable for use on stainless-steel fretwire, with the exception of our Fret Tang Nippers and Fret Cutters. Modern stainless-steel fretwire is known to be harder than the traditional nickel-silver blends, but our own shop experience indicates the wire does not cause premature wear of files or sandpapers.

I bit the bullet on this one and I'm glad I did. I bought the 300 grit ,couldn't be happier.

Offset Diamond Fret File (300 grit)

I used this item for the first time last week and was very impressed by how much easier and quicker it was to use than anything I have tried before. I have made one small modification, that is a push on handle to make it easier to grip and to save the end digging into the palm of your hand, (put that down to old age and arthritis!)

Best file ever!!

I purchased the 300 grit, very smooth and no chatter. High quality and sharp and works wonders over the body of classical and acoustic guitars. A little pricey but who else has one this nice; that's the reason for the 4 star?

Best fret file

I've used a Stew Mac fret file for about 15 years and it's still as good as new and quickly reshapes fret crowns after dressing

I could not do without

Since I bought the 300 grit file,that is the file I reach for all the times I do crowning works.

Guess I'll buy that 150 grit soon.

It would be even better if the wide and medium side where clearly marked, they are a little tricky to identify.

Best crowning file

Tried a lot of fret files, but this is the best. I agree that the 150 grit can be a little too aggressive, so I will mostly be using the 300 grit I guess. Other than that, there is no file that gives such a control over what you're doing, even when working over the body of the guitar.

A Must Have

I used this file on a acoustic last week.You can file over the body of any guitar without hitting the body.I couldn't have did the job without it. A must have for sure. I took a marker and marked one side medium and the other wide. That way I know right away what grit I'm sanding with. I love it.

Great Tool would like to see more....

This tool really gets the job done quickly and easily. I would like to have a better selection of widths and also an extra fine version and then would give it 5 stars

Great file with a downside to it...

By Dr Fretgood from Chicago IL

I recently purchased this file because the 300 grit was on back order and I needed a new file (my old 300 is pretty worn right now) The 150 grit is great, removes a lot of material with very few strokes, but the downside to it is that it scratches the fret a bit too much, so the time you save re-crowning you spend it removing scratches. Other than that I love them both 150 and 300 grit

Great file!

Until buying this file (300 grit) I had never crowned a fret. I found it very easy to use and, when combined with polishing the frets with 400, 600 and 1500 grit black wet/dry sandpaper, my frets were super smooth. Bends are much, much easier --- even on my PRS that is only a year old. I noticed that after the crowning and polishing that all my guitars have more of a ring to them. I've since done five other guitars for people and each one notices better sustain and more of a ring from their guitars.


I highly recommend this easy-to-use and (to me) indispensable tool!
